How often should I grind?

Reel grinding should be done when the adjustment and backlapping procedures are no longer effective, and before the grass is not cut cleanly. The following are some “general” time frames that can be estimated for grind intervals:

  • 8” - 10” Diameter ROUGH MOWER reels: Should be backlapped “as needed”; if estimated use totals 15-20 hours of cutting per week, this will yield a need to grind approximately every 400-500 hours, or once every six to eight months.
  • 5” - 7” Diameter FAIRWAY/TRIM reels: Should be backlapped “as needed”; if estimated use totals 20-30 hours of cutting per week, this will yield a need to grind approximately every 375-425 hours, or once every four to six months.
  • 5” Diameter GREENS & TEE MOWER reels: Should be backlapped “as needed”; if estimated use is five to seven times per week, averaging 15-25 hours of cutting time, this will yield a need to grind approximately every 200-250 hours, or once every three to four months.

The grind intervals noted above are strictly estimates. The need to grind depends on course conditions, top-dressing practices, adjustments, backlapping and/or nonbacklapping practices, and ultimately, the judgment of desired cut quality.

A special note should also be made that if you are relief grinding, your grind frequency will go down as longevity of staying on cut goes up.
